Most Versaflex™, Dynaflex™ and OnFlex™ materials (and Versalloy™ TPV alloys) are suitable for two-shot or insert molding onto a PP (and in some cases, PE) substrate. This will promote ease of dispersion. • Styrenic (PS) color carriers are recommended for the SBS formulations. • Polypropylene (PP) carriers are recommended for the harder SEBS formulations. • For soft SEBS formulations low-density polyethylene (LDPE) or ethylene vinyl acetate copolymer (EVA) have been used. PP carrier is not recommended for softer grades, as the compound hardness will be affected.

Garratt’s metrics changed during the year from PPS metrics to consolidated PolyOne metrics and, as a result, his 2016 payout was prorated based on his earnings under each respective metric. More recent performance in the CAI, SEM and PPS segments has been offset by the aforementioned macro- economic headwinds, as well as underperformance by our Designed Structures and Solutions segment. Garratt, who had previously served as Senior Vice President, PPS, was named as Senior Vice President, Chief Commercial Officff er on April 18, 2016.

However, as a result of the divestiture of the Performance Products and Solutions segment (PP&S) on October 25, 2019, we have removed PP&S as a separate operating segment and its results are presented as discontinued operations. Note 3 — DISCONTINUED OPERATIONS On October 25, 2019, we divested the PP&S segment for $782.1 million cash. For the income tax impact associated with PP&S, refer to Note 3, Discontinued Operations.
